Energy especially steam plays an important role in a process plant, especially in a petrochemical plant, which contributes 15% to 20% of the Cost of Goods Manufacturing (COGM). This research is based on the problem of increasing steam consumption in a fertilizer plant. The study is aimed to explore the factors that affect energy consumption and give recommendations to improve production performance. Data collection involves an initial survey to assess the current state of plant operation, encompassing steam consumption and heat dissipation. Thermal imaging inspection is used to identify the health of pipeline insulation. The findings underscore the performance degradation of steam pipeline insulation even visually it was normal. The prior solution to address the problem is the replacement of the damaged steam pipeline insulation. These solutions are projected to provide annual savings of 0.6 million USD/yr with a payback period of just 4 months.
